Expanding complex numbers
Did you know?
WebThis is an interesting question. The real numbers are a subset of the complex numbers, so zero is by definition a complex number ( and a real number, of course; just as a fraction is a rational number and a real number). If we define a pure real number as a complex number whose imaginary component is 0i, then 0 is a pure real number. WebA complex number is a number of the form a + b i where. a. a is the real part of the complex number. b. b is the imaginary part of the complex number. If b = 0, then a + b i is a real number. If a = 0 and b is not equal to 0, the complex number is called a pure imaginary number. An imaginary number is an even root of a negative number.
WebMar 26, 2016 · For example, to expand (1 + 2i)8, follow these steps: Write out the binomial expansion by using the binomial theorem, substituting in for the variables where … WebWell sure, you can use binomial theorem and expand the power. For even powers, you can first square the complex number, and then take that result to half the original power which can be quick depending on the complex number and the exponent. But using exponential form and de'Moivre is a lot easier and less time consuming.

WebA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a …
where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions cosine and sine respectively. This complex exponential function is sometimes denoted cis x ("cosine plus i sine"). The formula is still valid if x is a complex number, and so some authors refer to the more … See more Euler's formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function. … See more The exponential function e for real values of x may be defined in a few different equivalent ways (see Characterizations of the exponential function).

So x^2 + 9 = 0 gives x^2 = -9, and there is no real number that can be squared to give a negative answer, so we have to go into the imaginary numbers. To get your answer, you need a difference of perfect squares (x^2 - 9).
